MI TER BOX Filed Oct. 13, 1926 2 Sheets-Sheet 2 Inventor 52%0/2/ Attorney Patented Dec. 3, 1929 i UNHTED STATES PATENT OFFICE SAMUEL D. PEALER, F GHAGRIN FALLS, OHIO MI'IER BOX Application filed October 13, 1926. Serial No. 141,380.
This invention relates to an improved from one longitudinal edge of this base is the miter box which has been designed primarily backing member 2. This is preferably in the for use by carpenters and Wood-working form of a metal plate having a shoulder 3 men for accurate cutting oi the work at (see Fig. 3) at its bottom resting on the top hand. of the base. That portion 4; which depends Briefly, the invention has reference to a below the shoulder is provided with screwstructure of this kind which embodies a base threaded bosses 5 through which retaining and an upstanding backing member for the screws 6 are threaded (see Fig. 5). Formed work together with a novel adjustable sawon that portion of the backing plate extendcarrying and guide unit including accurate ing above the base are spaced parallel vertimeasuring and indicating means for permitcally xtending ribs 7, the abutment surfaces ting the blade to be disposed at the desired of which are accurately finished. As shown angle with respect to the base and back memin Fig. 2 a central opening 8 is formed in said her to produce a desired angular cut of the backing plate to accommodate the saw blade.
o k, From this it will be seen that the backing The structure has been designed for use plate will be readily attached to or removed with either a back or panel saw and the strucfrom the base. Attention may be also called. ture is such as to permit an angular cut of here to the fact that the small central portion sixty degrees on each side of the transverse of the backing plate is provided with a rela 2o center of the base, thus allowing a combined tively large centrally disposed socket 9 and measurement of 120 in order to permit mion opposite sides of this with smaller sockets nute adjustments of the saw for accurately cutting the work at an appropriate angle. The saw is generaly designated by the ref- An equally important object is to provide erence character 11 and it will be noted that 25 a comparatively simple and inexpensive the same provided with a rigid back 12. A.
structure wherein all of the parts are asnovel guiding and elevating unit generally sociated in a novel manner and are detachdesignated by the reference character 13 is ably connected together so as to permit the employed for supporting and guiding the entire structure to be knocked down and the saw. This unit comprises a special head parts arranged in a compact and convenient which includes pairs of olltwzu'dly convergan arrangement for carrying in a comparativeing arms 14: terminating in guide eyes 15 ly small tool box. carrying set screws 16. These arms are in Other features and advantages of the integrally connected at their inner ends with vention will become apparent from the i olopposite sides of a collar 17 (see Fig. l) and :3 lowing description and drawings. it will be noted that the upper side of this a" In the drawings: collar is beveled as at 18 and provided with Figure 1 is a top plan view of the complete graduations. In addition, the top of the d i collar is counter-bored to receive the flange Fig. 2 is a rear elevation, 19 on the upper end of a rotary bushing 20.
43 Fig. 3 is a central transverse section Formed integral with this bushing and more through the structure, particularly the base portion 21 thereof is a Figs. 4 and 5 are enlarged detail sectional special frame 22 constituting amounting and views and carrier for the saw. As shown better in Fig.
Fig. 6 is also a detail view showing the 6 adjusting screws 22 are provided on the 4;: manner in which the saw blade cooperates frame and bear against opposite faces of the with a supporting and carrying frame. blade of the saw thus permitting it to be Referring to the drawings in detail, it will held in a true vertical position. Connected be seen that the reference character 1 desigto the lower bars of said frame and located nates the base which is in the form of smooth in a vertical line beneath the outstanding as timber of appropriate proportions. Rising base portion 21 of the aforesaid bushing 20 is a split collar 23. In this connection, I would state that the'first-named collar 17 is made up of half-sections provided with outstanding ears 24 through which clamping bolts 25 extend. Moreover, a U-shaped bail 26 is pivotally mounted upon suitable brackets 27 on the upper end of the bushing 20. This bail carries a centrally disposed latch 28 having a detent 29 on its under side adapted to press upon the graduated periphery 18 of the colar 17. This is shown better in Figure 3. Here, I might state that if desired the graduations may be in the form of small notches for reception of the detent 29. This will insure positive maintenance of the latch. In addition, a suitable spring 30 is employed, connected to the bushing 20, and also to the latch 28 as shown in Figure 1 thus pressing the detent firmly down upon the collar. The detent also acts as an index or indication finger. I
In order to swinga-bly mountand maintain the unit just described in operative post tion I employ a central standard 31 having a vertically elongated slot 32 for reciprocatory movement of the blade of the saw. It is this standard which is surrounded by the bushing 20 and also the lower collar 23. Cooperating with the standard are upstanding guide posts 33 upon which the guide eyes 15 are slidably mounted. The posts 33 are detacl ably fitted in the aforesaid sockets 10 while the standard 31 is rotatably itted in thecentral socket 9. The opening 8, of course, accommodates, the swinging movement necessary in the adjustment of the saw.
Assuming now that thestructure is setup for use as shown in the drawing, it is obvious that the work is placed upon the top of the base 1 and forced firmly against the ribs 7. .In this connection, these ribs act as a straight edge. If desired, suit-able supplemental clamping means (not shown) may be employed for holding the work firmly in this place. Of course, when the work is thus placed in position, it is necessary to elevate the saw which is attached to the frame 22. This may be easily done inasmuch as the entire unit 13 may be slid upwardly upon standard31 and the guide-posts Then, the saw and unit is adjusted to produce the de sired angular out In order to do this, the latch 28 is lifted against the tension of the springs 30. Then the relatively movable part of the unit comprising the frame 22 and the bushing 20and the collar 23 and standard 31 may be swung and adjusted with respect to the stationary part 17 and arms 14.
The detent 29 of the latch is now seated in tile desired keeper seat on the graduate: dial 18.
Before the frame can be swung toadjust the angular position of the saw, it is of course necessary to loosen the set screw in the socket 9 which releases the standard 31 at this time. This allows the standard, the frame, and the saw, as a unit to be swung to the desired adjusted position. Of course, after the adjustment is made, the set screw in the socket 9 is again tightened, to hold the standard at this place.
It is thought that by considering the description in connection with the drawings, a clear understanding of the construction and the operation of the invention will be had. In view of this, a more lengthy description is thought unnecessary.
lVhile the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
I claim:
In a miter box structure of the class de scribed, a base, a work backing plate rising vertically from the base, said plate having an opening for swinging adjustment of a sa\ :1. rotatably mounted slotted standard disposed in alinement with the opening in said backing plate, stationary guide posts mounted on opposite sides of the standard and at the ends of said opening, a graduated collar surrounding and slidable upon said standard, spider arms connected at their inner ends to said collar and extending outwardly therefrom and provided with guide eyes, said guide eyes being slidably mounted upon said posts. and a saw carrying frame rotatably mounted upon said collar and slidably mounted upon said standard and including an indicator cooperable with the graduations on said collar.
In testimony whereof I aflix my signature.
